Boron doped graphene based linear dynamic range photodiode
Dere, A.; Coşkun, Burhan; Tataroğlu, A.; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed A.; Alateeq, Hind M. A.; Yakuphanoğlu, F. (Elsevier Science Bv, 2018)The boron-doped graphene oxide film was prepared using drop casting/coating technique. The film was coated by hydrothermal method on p-Si substrate and thus Al/p-Si/B-doped GO/Au diode was fabricated. The structural ... -
Graphene Oxide/Poly(3-hexylthiophene) Nanocomposite Thin-Film Phototransistor for Logic Circuit Applications
Mansouri, S.; Coşkun, Burhan; El Mir, L.; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed; Yakuphanoğlu, Fahrettin (Springer, 2018)Graphene is a sheet-structured material that lacks a forbidden band, being a good candidate for use in radiofrequency applications. We have elaborated graphene-oxide-doped poly(3-hexylthiophene) nanocomposite to increase ... -

Coşkun, Burhan; Mensah-Darkwa, K.; Soylu, M.; Al-Sehemi, Abdullah G.; Dere, A.; Al-Ghamdi, Ahmed; Yakuphanoğlu, Fahrettin (Elsevier Science Sa, 2018)In this work, 3% Fe doped zinc oxide (ZnO) doped by Nitrogen thin films were grown by reactive radio frequency magnetron sputtering on p-Si substrates. The structural and optical properties of the 3% Fe doped ZnO doped by ... -
Optoelectronic investigation of Cu2FeSnS4 quaternary functional photodiodes with IR detection capabilities
Koç, Mümin Mehmet; Dere, Ayşegül; Özdere, Alper; Al-Sehemi, Abdullah G.; Coşkun, Burhan; Al-Ghamdi, Ahmed A.; Yakuphanoğlu, Fahrettin (Elsevier, 2021)Cu2FeSnS4 semiconductor used in the preparation of quaternary photodiodes was synthesized using hydrothermal synthesis. The nanoparticles were then spin coated on a silicon substrate. Nanoparticles were characterized using ... -
The The validity of Kohlrausch law for the photocurrent transient and the role of N-2/Ar flow ratio in photoconductivity of sputtered CoZnO
Soylu, M.; Coşkun, Burhan; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed A.; Yakuphanoğlu, Fahrettin (Elsevier Science Sa, 2017)Co:ZnO (CZnO) ferromagnetic semiconductor layers are coated on the surface of glass and Si substrates by Magnetron Sputter Deposition Method (MSDM) with variable N-2/Ar gas flow ratio. N-2/Ar flow ratio varies from 5 sccm ... -
